Pushbutton-type Photomicrosensor
EE-SA701/801
Using a pushbutton enables
accurately detecting difficult-to-detect
objects.
• Conforms to standards for semiconductor FOUP cassettes to enable
accurately detecting FOUP cassettes without being affected by the
material, color, or reflectance of the bottoms of the cassettes.
• Thin design enables mounting in a wider range of applications, e.g.,
on transfer arms.
• Increased visibility with 4-direction indicator.
• Optical detection of actuator operation provides a long life
(mechanical life: 5 million operations min.).
• Models available with PNP or NPN output.
• Models are available with very flexible robot cable.
Be sure to read Safety Precautions on
page 119.
